protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
    {
        if (e.Item.ItemType == ListViewItemType.DataItem)
        {
            HtmlTableCell lblpwdHeader = (HtmlTableCell)this.ListView1.FindControl("tdColumn");
            HtmlTableCell tdPwdData = (HtmlTableCell)e.Item.FindControl("tdPwd");

            if (lblpwdHeader != null)
            {
                lblpwdHeader.Visible = false;
            }
            if (tdPwdData != null)
            {
                tdPwdData.Visible = false;
            }
        }
    }

Use the following Event: ItemDataBound, and use DataBinder.Eval(e.Item.DataItem, "NewsDate") which is equivalent to this <%# Eval("NewsDate") %>.

Here's the syntax to get the Label Control:

Label lbl = (Label) Item.Controls.FindControlByID("GreenDate");
